BackgroundConstrictive pericarditis is a rare and disabling disease that can result in chronic fibrous thickening of the pericardium. The purpose of this study was to evaluate the long-term outcomes following treatment of constrictive pericarditis by pericardiectomy.MethodsBetween September 1992 and May 2014, 47 patients who underwent pericardiectomy for constrictive pericarditis were retrospectively examined. Demographic, pre-, intra- and postoperative data and long-term outcomes were analyzed.ResultsThirty of the patients were male, the mean age was 45.8 ± 16.7. Aetiology of constrictive pericarditis was tuberculosis in 22 (46.8 %) patients, idiopathic in 15 (31.9 %), malignancy in 3 (6.4 %), prior cardiac surgery in 2 (4.3 %), non-tuberculosis bacterial infections in 2 (4.3 %), radiotherapy in 1 (2.1 %), uraemia in 1 (2.1 %) and post-traumatic in 1 (2.1 %). The surgical approach was achieved via a median sternotomy in all patients except only 1 patient. The mean operative time was 156.4 ± 45.7 min. Improvement in functional status in 80 % of patients’ at least one New York Heart Association (NYHA) functional class was observed. In-hospital mortality rate was 2.1 % (1 of 47 patients). The cause of death was pneumonia leading to progressive respiratory failure. The late mortality rate was 23.4 % (11 of 47 patients). The mean follow-up time was 61.2 ± 66 months. The actuarial survival rates were 91 %, 85 % and 81 % at 1, 5 and 10 years, respectively. Recurrence requiring a repeat pericardiectomy was developed in no patient during follow-up.ConclusionPericardiectomy is associated with high morbidity and mortality rates. Cases with neoplastic diseases, diminished cardiac output, cases in need of reoperation are expected to have high mortality rates and less chance of functional recovery.
ObjectiveTo investigate the impact of gender difference in early postoperative
outcomes in elderly patients (aged 70 or older) undergoing coronary artery
bypass grafting surgery.MethodsBetween October 2009 and December 2013, a total of 223 elderly patients (aged
70 or older) undergoing isolated primary coronary artery bypass grafting
surgery were included in this retrospective observational cohort study.
Patients were divided into two groups according to their gender. The
patients' medical records were collected, their baseline preoperative
characteristics, operative data, and postoperative outcomes were
retrospectively reviewed, and the effect of gender difference in the early
postoperative outcomes was analyzed.ResultsGroup 1 (female patients) and Group 2 (male patients) consisted of 71 and 152
patients, respectively. Mean age of patients was 74.4±3.6 years
(range: 70-84 years). The level of EuroSCORE I, the incidence of
hypertension and hyperlipidemia were significantly higher in Group 1, while
the rate of smoking was significantly higher in Group 2. Mean postoperative
intubation time, length of intensive care unit and hospital stay were longer
in female patients than in male patients, but these differences were not
statistically significant. No statistically significant difference between
two groups in terms of the transfusion of blood products was observed. The
rates of in-hospital mortality and major postoperative complications were
statistically similar between the two groups.ConclusionIn conclusion, the female gender was not associated with worse early
postoperative outcomes in elderly patients undergoing coronary artery bypass
grafting surgery.
Pericardial adhesions complicate re-operative cardiac surgery and several attempts have been made to reduce adhesion formation. The efficacy of bio-absorbable oxidized regenerated cellulose in preventing post-operative pericardial adhesions was evaluated in the present study. Forty New Zealand white rabbits were divided into four groups of 10. In all rabbits an area of pericardium (2 x 2 cm) was excised. The wound was left open in groups 1 and 2 but replaced with bio-absorbable oxidized regenerated cellulose in groups 3 and 4. Rabbits in groups 1 and 3 were killed 3 weeks after surgery and those in groups 2 and 4 were killed at 6 weeks. Groups 1 and 2 showed more severe pericardial adhesions, more fibrous reaction and increased visibility of coronary vessels than groups 3 and 4, although there was no difference in inflammation. Light microscopy showed a mesothelium-like cell layer in groups 3 and 4. It is concluded that bio-absorbable oxidized regenerated cellulose may be suitable in patients receiving staged cardiac surgery and in those with a high probability of re-operation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
